For those going to @ncmsociety.bsky.social annual meeting next week, come check out our posters! @diedrichsenjorn.bsky.social @gribblelab.org. I know that @mnlmrc.bsky.social @sivanjo.bsky.social @alighavampour.bsky.social @arminpanjehpour.bsky.social and Amin are excited show you what they've done.

What are the real promises and looming perils of neural foundation models? 🧠
I put my thoughts on (virtual) paper for @thetransmitter.bsky.social following a very energised workshop at @cosynemeeting.bsky.social 2025.

It's also my first piece for them 😊

Inhibitory normalization of error signals improves learning in neural circuits Normalization is a critical operation in neural circuits. In the brain, there is evidence that normalization is implemented via inhibitory interneurons and allows neural populations to adjust to chang...

How do neural circuits in the brain implement normalization? 🧠

In our new paper, we show that just normalizing sensory input isn't enough. Crucially, we must also normalize the error signals! 🧵👇

JEDI: Jointly Embedded Inference of Neural Dynamics Animal brains flexibly and efficiently achieve many behavioral tasks with a single neural network. A core goal in modern neuroscience is to map the mechanisms of the brain's flexibility onto the dynam...

New paper! We introduce JEDI, Jointly Embedded Dynamics Inference for neural dynamics.
arxiv.org/abs/2603.10489. JEDI flexibly infers dynamical principles (across behaviors/contexts) from neural population data through RNNs constrained at single-neuron resolution to reproduce that data.

New paper hot off the (pre-)press! We dig into the evolutionary origins of neural computations for behavioral control across mice, monkeys, and humans: www.biorxiv.org/content/10.6....

As our lab's first foray into comparative analysis of neural dynamics, I’m super excited about this work! 1/18

I want to write a fun little post on what we've learned in neuroscience in the last 20 years. What are the most interesting results you can think of? Biggest trends?

New paper out in Nature Communications about how object identity information evolves across sensorimotor cortex through grasp — and I am really happy with how it turned out. www.nature.com/articles/s41...

Do you observe these issues with value functions instead of Q-values? I’ve had much less issues with value functions than Q-value based algorithms in the past and wondering if this relates

While I'm sad to step away from my full-time academic work, the first few months have been fantastic—I'm enjoying doing exciting research at the scale possible in such an ambitious team and company. There's a lot to learn and I'm grateful for my inclusive colleagues enabling this experience.

The view a Research Scientist may enjoy running in Central Park

Happy to announce that as of this summer, I've joined the CTRL-Labs group at Meta Reality Labs as a Research Scientist! I've also relocated to the bustling city of New York, where I hope I can do my best work (and enjoy running in Central Park).

Yes! The advantages are much clearer wrt neural computation (memory, expressivity, and gradient propagation) than for exploration per se.

Learning through motor noise (exploration) is well documented in humans (lots of cool work from Shadmehr and @olveczky.bsky.social) but the scale is rather small. Here if the dynamical regime helps exploration I’d say it should be within these scales as well.

That being said this is not how we move (execute movements) and in that sense this is a model of learning rather control.

I would say yes it’s possible. Particularly because a deviation is carried over instead of collapsing back, so the filtering function that non linear muscle activations have will not impact it as much as white noise.
